If you look at the world population today, you'll see that India and China have populations of similar sizes — about 1.4 billion people each. However, the United Nations projections for these two countries over the rest of this century are miles apart.

Redditor u/petnog graphed out the UN's population projection by country (plus the European Union as a group) from this year, 2050 and 2100. While India and China stay in positions one and two, respectively, the former country's population stabilizes while the latter country's numbers plummet.

Over the next 26 years, India's population is expected to grow by 229 million and reach 1.6 billion, then dip to a total of around 1.5 billion people by 2100.

Meanwhile, China is expected to dip by 159 million by 2050 (to 1.2 billion) and then further fall down to 633 million by 2100.

Similarly, the 27 current European Union members are expected to lose population quickly. The UN projects that they'll be down 29 million people in 2050 (to a total of 422 million), and then end up with just 348 million by 2100.

So, what about the US?

By 2100, we do drop a few spots down to sixth place. Over the next few decades, our population is actually expected to grow by 36 million by 2050, and then crest at a total of 421 million in 2100, when Pakistan, Nigeria and The Democratic Republic of the Congo blow past us.
